Description: ：在深海采矿环境中超声波传输介质里存在着大量气泡、扰动沉积物、机械噪声等背景噪声与混响，导致有用信号与高
噪声信号迭加在一起，严重影响了测距精度。采用小波分析方法将超声回波信号进行3层小波分解，适当设置门限阈值对小波
系数进行处理，然后对信号进行重构，有效地抑制了信号中噪声对测量精度的影响。研究结果表明：小波方法有很好的降低回
波信号中噪声的效果，其测距精度高于自适应滤波去噪后的测距精度。-There are much background and mixture noise in the course of ultrasonic wave transmission under deep
sea mining environment，such as air bubbles and disturbed sediment and mechanical noise．Because of these factors，
the useful signals and the high noise signals are combined together，which seriously affects the distance measurement
precision．Ultrasonic echo signals are decomposed into three layer wavelets，and a threshold is set to process the
wavelet coeficients．Then the signals are reconstructed．Accordingly the influence of environment noise on distance
measurement precision is effectively restrained．Research resuhs indicate that wavelet transform method is very useful
for noise reduction in signals．Its precision is higher than that of the adaptive filtering method．

Description: 湖南省含锰沉积层的层位有下震旦统莲沱组、上震旦统陡山坨组、中奥陶统磨刀溪组、下二叠统当冲组和上二叠统长兴组等十个层位。赋存在这些岩组中的沉积碳酸锰矿或含锰灰岩露出地表以后，在湿热气候条件下经表生风化作用使锰质进一步富集，形成我省较为重要的锰矿类型。这种矿床按其成因可分为锰帽、淋滤和堆积三大类。-Hunan manganese sediment layer bit lower Sinian liantuo Group, Upper Sinian Doushantuo lump Group, Middle Ordovician Brothers River Group, Lower Permian when the red group and the Upper Permian Changxing Formation other 10 layers. Fu existence of these groups of sedimentary rocks manganese carbonate or manganese exposed limestone surface after the hot and humid weather conditions in the supergene weathering by making further enrichment of manganese to form manganese province of the more important types. Such causes can be divided according to their manganese deposit cap, leaching and accumulation of three categories.
